In the arrangement shown, the heater comprises a main or body member,v7, and a cover plate, 8, of any suitable material; the body member 7being in the form of a shallowbox or receptacle having a flat bottom,the central portion of which is horizontal while the rear portion, 9, isinclined upwardly and the front portion, 10, is inclined downwardly. Inthe center of the horizonytal portion of the member 7 is an opening,'11, large enough to permit the passage ,30 of the exhaust nozzle, theopening 11 being surrounded by a continuous wall, 12, whose height isjust equal to the height of the side and end walls, 13. It is customaryto provide the exhaust nozzles with projecting flanges in proximity tothe upper ends and therefore when ythe heater is slipped down over thenozzle it rests upon and its weight is carried by the fiange 14 on thenozzle. All of the Water 4o which enters the gas heater comes in at thebottom while the water passing out of the heater leaves it at the top.

In the arrangement shown, there are two feed water inlet openings, 15and 16, ar-

ranged in the two side Walls of the'heater close to the lower end, andthere are two outlet openings, 17 and 18, arranged in the two. sidewalls of the heater near the top. Vithin the interior of the heaterbetween .5o the inlet openings and the delivery openings I arrange aseries of transverse deiecting partitions none of which extendscompletely across the heater, the openings left for the passage of waterpast the parti- 5 5 tions being staggered relative to eachother so thatthe water cannot flow in a straight line. In the particular arrangementshown, the lower inclined portion of the heater has a transversepartition, 19, arranged above 6o the inlet openings and cut away at thecen-Y ter. The front portion of the wall 12 has laterally extendingwings, 20, which do not reach quite to the side walls of the heater.Toward the rear of the horizontal portion of the heater are two shortpartition members, 21, 21, extending inwardly from the side walls butnot reaching the wall 12. y

Behind and above the members 21, 21, are two comparatively longpartition members, 22 and 23, extending from opposite sides of theheater more than halfway across the same; and between the member 23 andthe delivery openings are partition members,

24, 24, extending from opposite sides of the ,front sheet of the boiler,the body portion of the heater beingprovided with aperforated flange,25, to which suitable attaching and bracing devices may be fastened; the

arrangement being preferably such that the heater forms a partitionextending forwardly and downwardly from the front sheet of the boilerfor the full width of the smoke box, so that none of the hot gases canescape without iiowing down beneath the lower front edge of the heater.

The inlet openings 15 and 16 of the heater are connected to pipes, 30and 31, each of which is supplied with feed water in any suitable way.The delivery openings 17 and 18 are connected to the interior of theboiler by means of valved pipes, 82 and 33. In accordance with onefeature of my 4invention I also connect the lower portion of the heaterwith the lower portion of the boiler where the water is usually cool ascompared with the Water from' which the steam is being evolved. In thearrangement shown, I have provided a separate valved pipe, 3-1, betweenthe lower end ofthe heater and the bottom of the boiler, the pipecontaining also a check valve, 35, which will prevent the water fromflowing through the connection toward the boiler. The pipe mayconveniently be connected with the pipe 30 just before the latter pipeenters the shell of the smoke box, thus bringing the pipe 34 and itsvalves outside ofthe smilie box.

With the arrangement 'described feed water can be delivered tothe boilerfrom either or both injectors, first passing through the heater 'andhaving its temperature raised so that it enters the boiler as hot water.Furthermore, there may at all times be a. circulation of water from thebottom of the boiler through the heater and back into the top of theboiler so that even when the locomotive is standing still and no wateris being delivered to it, some of the heat of the combustion gases willbe utilized toheat the comparatively cool water in the bottom of theboiler.

All locomotives are now equipped with kl A. Stes the,

which receives the exhaustv steanifrom the air pump. The feedv water,from one of the injectors may be of the heater being connected to thepipe.'

30which is one of the supply pipes for the gas heater. The heater 40 isprovided with a suitable discharge pipe, 43, for steam which is notcondensed in the heater and with a suitable drip pipe, 44, through whichthe water of condensation may be discharged. In addition to the steamfrom the 'air pump the exhaust steam heater may also receive steam fromthe main cylinders of the engine; a connection, 45, between the heater40 and the exhaust side of the engine cylinders being provided for thispurpose. .The pipes 30 and 32 are connected by a Aviali/'ed branch pipe46 and between the pipe 46 and the heater 40-'i`s arranged a checkvalve, 47, which will prevent' back yflow of water from the boiler. Thenthe valve in the pipe 4G is closed and the injector is started, the feedwater will flow through the exhaust steam heater 40, through the gasheater 6 and then to the boiler.

W'hen it is desired to cut out the Vgas heater, valves 48 and 49arranged respectively in the pipe 8O and in the pipe 32 between thebranch 46 and the gas heater are closed and the valve in the pipe 46 isopened. The feed water will now flow directly from the exhaust steamheater through the branch pipe 4G and into the boiler without goingthrough the gas heater.

lt will thus be seen that lAhave provided a simple and novel arrangementfor simultaneously controlling the flow of the gaseous products ofcombustion and transferring a large part of the heat content therein tofeed water for the boiler and have also provided a simple arrangementfor utilizing the exhaust` steam from the air pump for the purpose ofheating feed water and at the same time overcoming the objectionable ifeature of a wet sooty discharge from the carried into the heater40,thF-Qllgh thppeif, the dSChm'g@ @nd yprovided, a'simpl'e: jv.l)iroduc-ing circulation 'ofl the water i boiler. ,andi transferringheat fromQthe :f cool water .in ther bottoni ofthe b'ol'iler .with5particularity 'fonlya -fornifof, my 'invc'ntion lido. not limitedijtothe exact structuraljf'de permittingfthe igas-llieate ous.:products.oflcoinbustion-'and' ilameftol illustrated' andfide's'cribedjf but`I ycover-,all forms .and arrangenientfs,-ii'vy i withinthe jterinslenployedin Fth v` of j .my .invention i, constituting h claims@A ff;
